Oleanolic acid (OA) and ursolic acid (UA) are isomeric triterpenes that are difficult to separate chromatographically. Studies have indicated that both OA and UA have antifertility properties in… (More)

Ostrich chick mortality was studied in 2522 chicks that were hatched artificially during the 1999/2000 breeding season. High levels of mortality were observed, with 1978 (78.4 %) of these chicks… (More)

The study provides information on the reproductive performance of ostriches maintained at different stocking rates and male:female (M:F) ratios under intensive commercial conditions in the Little… (More)

Microscopically evaluated sperm parameters, as well as computer-aided sperm motility analysis (CASMA), were used to assess sperm quality and the effect of cryopreservation on ram semen obtained from… (More)

The influence of extending the vaccination-to-slaughter interval of immunocastrated lambs on carcass cutting yield and meat quality of the Longissimus thoracis (LT) muscle was investigated in forty… (More)

This study determined the influence of varying intervals between second vaccination and slaughter of immunocastrated rams on carcass cutting yield and meat quality. Two booster vaccination intervals… (More)

Motility is an important criterion in the assessment and quantification of the quality of ejaculated and epididymal sperm samples. Ovine sperm spermatozoa are particularly susceptible to cryodamage,… (More)
